C₁₃H₁₄O₅ as Pharmaceutical Intermediates

Ethyl β-Oxo-1,3-benzodioxole-5-butanoate CAS 31127-23-8 is a β-ketoester derivative​ featuring a 1,3-benzodioxole (methylenedioxyphenyl) aromatic system. Structurally, it consists of a benzodioxole ring attached through a three-carbon chain to an ethyl β-ketoester functional group (-CO-CH₂-COOEt). This makes it a versatile bifunctional building block​ for organic synthesis, combining the electronic properties of the benzodioxole group with the high reactivity of a β-ketoester.
